Is This Electrocution Prank Funny or Mean?

The husband in this video very convincingly fools his wife into thinking she has electrocuted him while he's working on a light switch in their house.

It's really hilarious and we think you're going to, ahem, light up when you see it. But some may think that tricking your spouse into thinking they've killed you is a tad on the cruel side. What say you? Funny or mean?
